To uil 107mm t may Concern.' l lie it known that i, Janine @anni aan', a citi; oi' the `lllnited States, residing at, Pittsburg, in` the county of Contra `Costa and @tate ot' @aliifornimhave iuventedcertain new and useful improvements `in al liethe following to be a! tull, clear, anderer de; y,e invention,such as i 'llenf able others skilled in the art to whijclfiyit `ap- :giertaine to mai-te and use the name.

ilhie liinfcntion relates to a resilient object i tire, :o provide a tire olf .nich

an inner: tube, orpneumatic tube, is ob;-

` viated, the tirefper se providingthelneees-` sary resiliency. y i, y fi. turther object is to provide a tire oi; the type indicated., which .may be, so construct ed by employing` materialsofthe required strength that it will be suitable for all sizes and makes `oi" motor vehicles.

A still further object `is to provide for in.- creasing; the strength rntlie` tire impropertion to the load to be carried, by employing.; a wire .structure havingi certain novel characteristics which permit ot the distribution ol the loa d in a highly eiiicient manner, and `which at the same time provides the proper degree of resiliency and tractive power.

d, still further object is to provide particular means it'or mounting or securing the wire structure.

it. stili further object is to provide, in connection with the foregoing, an outer layer of rubber, a body of rubber intimately associated with the wire structure, a sut- `iicient number oit' layers ot canvas, and a wheel equipped with a tire and rim embody my; my invention, a `part of the tire being; broken away toillustrate the Wire mesh of my invention.

It body of rubber ltis intimately associated with the structure ot wire mesh, and is vulcanized thereto, and adjacent to the iu ner surface of the body la are the cords l5.

`and another layer oiE canvas i6 (constitutes the inner member of the tire.

Une oi the most important features ot' the construction is that involving` the wire mesh,

Oppostely located annular elements .i8

each comprise a portion 2l, a portion extending at an acute angle with referenceto portion 2l, forming a type of channel member, il-shaped in cross section, and the element 22 having` an oiiset Hanne 23. a. series oi teeth 2ais provided on the free edge ol' member 2l. These teeth are oft hook term and engage the selvagge of the ernbed'ded reinforcement by having' the strands 25 and 26 thereof looiped therearounr. (Fig. 4L).

lThe mesh comprises a Qlurality of wires 25 extending obliquely., and a plurality oit wires 25 extending' obliquely inanother direction, and passing around the tire. The

i aarticular anale at which the series 25 and o a sectional view taken onthe line a slight modiedges per sc Y anY enlarged portion 28 is molded for embedding the elements 1S and providingthe necessary flanges.

Spreading devices are provided at suitable kintervals and each include a plate 30 adapted to lie adjacent to the rim 31, and further include vengaging devices 32, riveted `to elements 30 and Vhaving the flared portions 3.3

and34. The V-shaped channels 35 are thus Vprovided for receiving the edge portions of thetires. The usual lugs, or Vsecuring devices for the tire, are shown, at 36, and the felly of the wheel is designated at 37. The

' Wire may be of brass or steel, the Vgage in a In Fig.

given instance dependingupon the ysize of `the tire and the Work which it is intended to perform.

i 8 I have shown a second layer of Wire mesh, 'the rubber being vulcanized around the -tWo layers, here designated 40 Aand 4l.v This structure is employed in tires designated for unusually Vheavy loads. aving thus described' the invention,

l wvhat I claim is:

l. A Vtire open upon its inner side and having thickened portions at the edges bor ydering upon the opening to form flanges, an-

nular members embedded 'in the flanges, each vderinguponthe opening to form flanges,an-

nular members embedded in the flanges, each member comprising portions disposed relatively at an acute angle to each other, one

of said portions having hooks along its free edge, and the other portion having its free edge offset, and a mesh reinforcement embedded in the tire and comprising obliquely disposed wires looped about the hooks of the said annular members.

3. A tire comprising an inner layer of fabric, a series of cords, a body of rubber, a metallic reinforcing structure for the latter comprising separate series of wires extending obliquely around the tire in two directions, spaced annular elements to which the Wires are secured, said elements being embedded in the rubber, a layer of fabric, and a tread portion for the tire.

4;. A tire comprising a series of wires extending obliquely around the tire in a given direction, a series extending obliquely around the tire in another direction, spaced annular elements for securing the individual Wires, and spacing elements for the annular elements, each of the spacing elements including a plate for contact with u wheel rim, and ared engaging devices connected with the plate and positioned for contact with the inner |portion of the tire at the edges thereof.

In testimony whereof I affix my signatuw in presence of two witnesses.
